there are patches out there for NFS UNderground. you can get them pretty much everywhere. just google it or go to the official website which will most likely have links or the file name (so you can google it). also with the patches im more then certain that there is a lan option (not 100% cuz i havent played the game in over 3 months). the internet is fine tho - just look for people with a low ping to cut down on the lag - which really doesnt matter since youre racing and not shooting each other.
